People have been requesting a production Mapper 30 flash cart programmer too. I kind of always thought this base was covered by 8bitheroes already but maybe there is still a need?
If you're willing to source your own components, do the soldering, and flash the chips, there's Muramasa and MouseBiteLabs.
Otherwise, there are a lot of N8 variants floating around (never tried them myself). There's also a "nes flashkit" on aliexpress I haven't seen before.
I would not recommend the kazzo flashcarts sold on aliexpress - the NROM one I and a few others got seem to be badly made to the point of being unusable. See here: viewtopic.php?p=303940#p303940
PCB stock on Homebrew Factory USA will be back very soon. Next shipment to our distributor partner Dalyen Games should leave next week.
If you have specific needs, feel free to contact us via e-mail directly.

Or DM Memblers for specifically GTROM
If you just need one GTROM board for testing/dev, I got permission from Joe to resell them individually to make the process simpler for acquiring one: https://www.bitethechili.com/developer-resources/
